随着水利水电工程的快速发展和施工技术的不断提高,越来越多的水利工程在丘陵山区建造,水工隧洞就是其工程的主体建筑之一。由于隧洞工程的工程量大,工序繁多,且受限制于地形因素,施工较为困难,因此对于水工隧道工程设计的合理性和高技术性就成为保证工程质量的关键。本文将结合具体的工程实例,从隧洞开挖、隧洞支护与衬砌、围岩的开挖与支护、混凝土衬砌、喷混凝土、隧洞灌浆等几个方面,探讨隧洞工程的设计技术问题。
With the rapid development of water conservancy and hydropower projects and continuous improvement of construction technology, more and more water conservancy projects are built in hilly areas. Hydraulic tunnels are one of the main structures of the project. Due to the large engineering quantity, numerous procedures, and limited topographical factors, construction of tunnel engineering is difficult. Therefore, the rationality and high-tech of hydraulic tunnel engineering design have become the key to ensure the project quality. In this paper, we will discuss the design technical issues of tunnel engineering from several aspects such as tunnel excavation, tunnel support and lining, surrounding rock excavation and support, concrete lining, sprayed concrete, tunnel grouting and so on.
